Publication
- OsTZF1, a CCCH-tandem zinc finger protein, confers delayed senescence and stress tolerance in rice by regulating stress-related genes, 2013, Plant Physiol.

Genbank accession number
Key message
- Histochemical activity of beta-glucuronidase in transgenic rice plants containing the promoter of OsTZF1 fused with beta-glucuronidase was observed in callus, coleoptile, young leaf, and panicle tissues
- Promoter GUS analysis revealed that OsOPT7 expresses in root tips, root vascular tissue and shoots as well as during seed development
- Furthermore OsOPT7 did not complement the growth of yeast fet3fet4 mutant
- Microarray analysis of OsOPT7 knockout 1 (opt7-1) revealed the upregulation of Fe-deficiency-responsive genes in plants grown under Fe-sufficient conditions, despite the high Fe and ferritin concentrations in shoot tissue indicating that Fe may not be available for physiological functions
- Iron deficiency regulated OsOPT7 is essential for iron homeostasis in rice.
- OsOPT7 localized to the plasma membrane and did not transport Fe(III)-DMA or Fe(II)-NA and GSH in Xenopus laevis oocytes
